Why “mind like water”?

Mindwtr takes its name from mind like water: a clear mind, ready to give each thing the attention it needs.

Start with a simple list and open advanced tools when you need them. If life gets busy, come back when you can. There are no streaks to protect or productivity scores to chase.

Method. Checked against official product, pricing, download, and help pages. “Full GTD” requires first-class Inbox, Next, Waiting, Someday, Review, and sequential projects. “All platforms” requires native apps for Linux, macOS, Windows, iOS, and Android. “No” means official sources do not document the capability; “Partial” means only part is supported. Sources: Mindwtr, Todoist plans, apps and offline mode, TickTick plans and apps, Everdo, and Nirvana.

Fit. Mindwtr is best for one person who wants a complete GTD workflow, local data, and optional user-chosen sync. It is not designed for shared workspaces, task assignments, or team discussion. See the product scope.

Automation and AI stay optional.

AI assistance is off by default. Connect your own provider or local model if you want it, or use the API and MCP to work with other tools.

This is by far the best GTD software I’ve used including two paid subscription ones. Cannot emphasize that enough.
James Discord
By default this app only shows the task being worked on instead of everything at once! This is amazing for not getting distracted by massive todo lists. … Also, this is local-only by default, with option to turn on iCloud and other syncs. Simple without all the extra junk no one actually uses. And no garbage AI!
Hamstercannon App Store
Just what I have been looking for: GTD at its best, local first, no cloud, no costs.
Philip Google Play
Exactly the kind of to-do app I’ve been looking for for so long. For Android, Linux, and macOS. Excellent data protection. Offline. Clear, minimalist design without looking ugly. And then it’s also free and open source…

Pretty solid cross-platform GTD app with various sync options. Not perfect, but very close to it, and the developer is super responsive.
Srijan Google Play
I yearned for GTD again and just cannot go back to Notion … I looked for 'Todoist open source' alternative and found this recent post. So grateful I did. I added a few tasks and … this feels fantastic!
NicoLargi Reddit
The best digital fast-capture GTD-oriented app I’ve ever used and rapidly improving all the time, and will always be free thanks to the creator’s licensing philosophy.
Jonathan Google Play
A revolutionary task manager application, I can note down anything, and process it later, encouraging me to think freely…
Richardo Google Playtranslated
I have used several TODO/Task apps in the past and have not much success with them i.e. I never Got Things Done! I have used Mindwtr for a few weeks now and I am very impressed and have actually managed to get a few things done.
